6 of the Biggest Flowers on Earth

Rafflesia arnoldii

More than its size, however, Rafflesia is known for its scent. Dubbed the "corpse flower," the large bloom reeks of rotting meat—an adaptation it has developed to attract the flies that help pollinate the plant.

The unusual flower only grows on the tendrils of the Tetrastigma vine, which in turn only grows in pristine rainforest—meaning Rafflesia arnoldii's habitat is rapidly disappearing.
